Abstract: Disclosed herein is a method of synchronizing the actions of one or more devices using an RF time signal. In one embodiment, a clock in a device is synchronized to an RF time signal, and the clock is applied in a timed event performed by the device. The timed event may include determining a time of occurrence of an event associated with the device or starting a process performed by the device at a predetermined time. In an alternative embodiment, the method includes: coordinating a first timed event to be performed by a first device and a second timed event to be performed by a second device; receiving an RF time signal at the first and second devices; synchronizing a first clock in the first device and a second clock in the second device to a time indicated in the RF time signal; applying the first clock in the first timed event performed by the first device; and applying the second clock in the second timed event performed by the second device.
